Hi there, looks like someone has confused you too much. Deep bite is a dental term which indicates that maxillary teeth are completely overlapping and hiding the mandibular teeth.. if so you can't have a maxillary discrepancy. Hence please take a lateral Cephalogram and consult an orthodontist before arriving at mis-interpretations, which might mis-direct your treatment outcome.
Next Steps
Visit an orthodontist with a lateral cephalogram
Health Tips
Take lateral cephalogram x-ray first.
